'Again,' says Grotius, 'it is plain that the world must have had a beginning, from the existence of mountains. For if the earth had existed from eternity, the mountains, which the rains and floods are always reducing, washing down particles into the valleys and plains, would long ago have disappeared, and every part of the earth would long before this have been quite level.' Here was another error. Grotius was not aware, it would seem, that there are forces continually at work in the interior of the earth making _new_ mountains,--that some portions of the earth are continually rising, and others gradually subsiding. 4. Several of the arguments which I met with in Doddridge's great work I found to be unsound. And there were others which, if I did not discover to be fallacious, I felt to be unsatisfactory. They were, in truth, as I afterwards found, mere metaphysical puzzles. 5. Among the most honest and earnest works on the evidences that came in my way, were those of Richard Baxter. But many of his arguments were unsatisfactory. Among other things of doubtful value, he gave a number of ghost stories, and accounts of witches and their doings, and of persons possessed by evil spirits, and even of men and women who had sold themselves to the devil, and who had been seized and carried away by him bodily, in the presence of their neighbors and friends. Then some of his arguments took for granted points of importance which I was particularly anxious to have proved. Much of his reasoning seemed conclusive enough, but when sound and unsound arguments are so blended in the same book, the unsound ones seem to lessen the credit and the force of the sound ones. On the subject of the evidences, Baxter, like Grotius, was behind the times. His works might be satisfactory enough to people of his own day, but they were not adapted to the minds of people of the present day. 6. The works of Paley and Butler gave me the greatest satisfaction. Paley, both in his Natural Theology and in his evidences of Christianity, seemed to be almost all that I could desire, and I rested in him for a length of time with great satisfaction. But I read him only once, and I ought, for a time at least, to have made him my daily study, and imprinted his work on my mind, as I did the work of Grotius.
